Abstract

Pemberian pupuk cendawan mikoriza arbaskular (CMA) dan pupuk NPK terhadap pertumbuhan dan produksi tanaman sawi (Brassica juncea) bertujuan Bagaimana interaksi antara pemberian pupuk CMA dan Pupuk NPK terhadap pertumbuhan dan produksi tanaman sawi (Brassica juncea). Penelitian ini di laksanakan di Lahan Pertanian UNIVA Simalingkar B, dengan ketinggian ± 15 meter di atas permukaan laut. Penelitian ini dilaksanakan mulai bulan Mei s/d selesai Faktor pertama dengan empat perlakuan pupuk CMA dengan dosis C0 0g, C1 30g, C2 60g, C3 90g Faktor kedua dengan empat perlakuan N 20 g/, 40 g, 60 g . Parameter penelitian ini adalah Tinggi Tanaman Sampel/Plot (cm), Jumlah Daun Tanaman Sampel/Plot (helai), Luas Daun, Bobot Basah, Bobot Basah Akar. Tanaman Tertinggi terdapat pada perlakuan C3 sebesar 10.71 cm dan tanaman terendah terdapat pada perlakuan C0 yaitu sebesar 8.39 Cm. Penggunaan pupuk NPK berbeda nyata terhadap tinggi tanaman sawi. . Dari hasil penelitian menunjukkan bahwa semakin tinggi jumlah pupuk CMA dan Pupuk NPK yang diberikan, menghasilkan pertumbuhan sawi (Brassica juncea) yang semakin baik pula. Hal ini dapat dilihat pada parameter tinggi tanaman Tanaman Tertinggi terdapat pada perlakuan C3 sebesar 10.71 cm , Jumlah daun tertinggi terdapat pada perlakuan C3 yaitu sebesar 9.36 helai daun, . Luas daun tertinggi terdapat pada perlakuan C3 yaitu sebesar 8.40 cm2, Bobot basah tanaman sawi tertinggi terdapat pada perlakuan C3 yaitu sebesar 3.80 gram, Volume akar tanaman sawi tertinggi terdapat pada perlakuan C3 yaitu sebesar 0.78 cm3.

Abstract

This study aims to evaluate the performance of rice farming based on differences in varieties used, namely national superior varieties, local superior varieties, and hybrids in rainfed rice fields. The research method used was a survey of rice farmers with a quantitative descriptive approach. The results showed that the highest productivity was obtained by the Super Bernas hybrid variety with an average production of 7,454 kg/ha/planting season, followed by the local variety Anak Daro at 6,746 kg/ha, and the national variety IR 42 at 6,417 kg/ha. The highest production costs were also found in the Super Bernas variety, but were offset by the highest net income of Rp6,809,118/ha. In terms of efficiency, the Super Bernas variety showed the highest RCR value of 1.36, which means it is more efficient than other varieties. Overall, hybrid varieties provide higher production results and income despite requiring higher production costs.

Abstract

Fall Armyworm (FAW) or armyworm (Spodoptera frugiperda J. E. Smith) is an insect native to the United States that is invasive to Indonesia. Pest control can be done with natural/biological compounds derived from plants which are an alternative to chemical insecticides. The purpose of this study was to observe the toxicity response of contact poison extract of Tithonia diversifolia kipahit leaves against S. frugiperda larvae. This study was conducted in the laboratory of the Faculty of Agriculture, Islamic University of North Sumatra, Jl. Karya Wisata Gedung Johor. Medan Johor District, Medan City, North Sumatra, with an altitude of ± 25 m above sea level (meters above sea level) with flat topography. This research was conducted from June 20, 2025 to August 16, 2025. This research used a non-factorial Completely Randomized Design using several treatments, namely k0: control, k1: 0.1%, k2: 0.2%, k3: 0.3%, k4: 0.4%, and k5: 0.5%. By using Analysis using IBM SPSS Statistic 20. Observed parameters S. frugiperda pest level, Lethal concentration LC50 and Lethal Time LT50. The results showed that the administration of kipahit leaf extract (T. diversifolia) using contact poison application in this study had a significant effect on the mortality of S. frugiperda larvae, the highest mortality was at a concentration of k5 (0.5%) which was 77.50%, the higher the concentration of contact poison given, the faster the mortality process of S. frugiperda larvae.
